Rose plant named Pekcoucan

ABSTRACT

A new rose plant producing orange red flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant producing hybrid tea type flowers rose class which was originated by my crossing as seed parent the variety known as `Pekom Ecli` and as pollen parent the variety known as `Korpek`. The varietal denomination of this new rose is `Pekcoucan`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its attractive well formed orange red flowers borne on a plant suitable for cut flower production and for growing outdoors in gardens. Flowers open well and hold their coloring as blooms age. Asexual reproduction by propagation by budding of the new variety as performed in La Petite Pierre, Wingen-Sur-Moder, France, shows that the foregoing and other distinguishing characteristics some true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. As can be ssen there is described a young stem shoot 1, green bud 2, buds showing color 3 and 4, opening flower 5, open flower 6, reproductive organs 7, 8 and 9, stems with prickles and thorns 10 and 11, and compound 3,7 and 5 leaflet leaves 12, 13 and 14.

DESCRIPTION OF THE NEW VARIETY

Pekcoucan is an unusually fine hybrid tea rose of orange red flower coloration. It may be used in gardens and for cut flower production under glass. The buds are well shaped and of good form and the flowers are 3 to 4 cm. in size.

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart.
